如图，源文件里肯定没有的，我发现我转码后的hevc，x265或者qsv265都会有这种阶梯锯齿状的问题，位置好像比较固定。好像avc里就没有。换了两个播放器好像都有。码率都提高到3300k
bp
s了。是不是在转码时加什么设置或者滤镜？

解码器换最新版的lav看看问题还存不存在。另外，成品的mediainfo？

第一个是meGUI用x265压

两个hevc文件，播放器无论是pot还是mpc，渲染器选EVR或者EVR CP或SVR都会出现上面那种阶梯锯齿，换madVR或者VMR或者Haali就没有。。。这是有什么特殊情况吗

默认解码器加EVR就是这样，用lav或者madvr随便一样就不会这样

EVR目前发现的唯一问题是对X265的亮红色显示存在问题 其它倒没发现问题 你可以看下POT的自推荐滤镜试试
